The utility model discloses a design quick detach structure realizes quick assembly disassembly electric motor rotor's purpose, simple structure, and convenient operation guarantees the leakproofness of protection casing behind the dismouting.
Description
Technical Field
The utility model belongs to the technical field of electric tool technique and specifically relates to electric motor rotor rapid disassembly structure.
Background
The motor is mainly used for generating driving torque and is used as a power source of electric appliances or various machines. The existing motor is generally provided with a protective shell for protecting the internal structure of the motor, and the protective shell is diversified in form.
When the motor rotor is damaged or needs to be maintained, the protective shell needs to be completely disassembled, and the motor rotor can be taken out, which is troublesome, and the fixed part between the shell parts is easily damaged in the disassembling process, so that the sealing performance after subsequent assembly is poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses not enough to among the prior art, provide electric motor rotor rapid disassembly structure, it realizes quick assembly disassembly electric motor rotor's purpose through design rapid disassembly structure, simple structure, and convenient operation guarantees the leakproofness of protection casing behind the dismouting.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the quick-release structure of the motor rotor comprises an upper shell, wherein a through hole is formed in the upper portion of the upper shell, above the motor rotor, and a sealing element is arranged at the through hole.
In the above scheme, preferably, the upper shell is provided with a positioning groove communicated with the through hole. The bottom surface of the positioning groove is provided with a mounting groove, and a sealing ring is arranged in the mounting groove. The shape and size of the positioning groove are matched with those of the upper part of the sealing element. Be used for matcing the sealing member through the design constant head tank, form the integral type structure, through design mounting groove and setting up the sealing member in the mounting groove, help promoting leakproofness, the waterproof nature of this through-hole position.
In the above aspect, preferably, the sealing member is a screw, and the sealing member is screwed to the through hole. Adopt screw and threaded connection's mode, easy dismounting and stable in structure after the installation, the leakproofness is good.
In the above scheme, preferably, the mounting groove is concentric with the through hole and has a diameter larger than that of the through hole. Helping to improve the sealing of the structure.
In the above scheme, preferably, the through hole is formed right above the motor rotor. The through holes are arranged right above the rotor, so that the rotor is detached most conveniently and smoothly.
The utility model has the advantages that: the utility model discloses a design quick detach structure realizes quick assembly disassembly electric motor rotor's purpose, simple structure, and convenient operation guarantees the leakproofness of protection casing behind the dismouting.
Drawings
Fig. 1 is a schematic view of the present invention.
Fig. 2 is a schematic view of the upper housing of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 and 2, the quick-release structure for the motor rotor comprises a shell 1, wherein an upper shell 11 and a lower shell 12 are arranged on the shell 1, the upper shell 11 is arranged at the top of the shell 1, the lower shell 12 is arranged at the bottom of the shell 1, the upper shell 11 and the lower shell 12 are fixed through fixing pieces, and the fixing pieces are preferably bolts.
A through hole 31 is formed in the upper shell 11 above the motor rotor 2, and preferably, the through hole 31 is formed right above the motor rotor 2.
Preferably, the upper housing 11 is provided with a positioning groove 32 communicated with the through hole 31, the bottom surface of the positioning groove 32 is provided with a mounting groove 33, and preferably, the positioning groove 32, the mounting groove 33 and the through hole 31 are concentric, and the diameter of the positioning groove 32 is gradually reduced from the positioning groove 32 to the mounting groove 33 to the through hole 31, namely, the diameter of the positioning groove 32 is the largest, and the mounting groove 33 is the second, and the diameter of the through hole 31 is the smallest.
And a sealing element 4 is arranged at the through hole 31, and a sealing ring 5 is arranged in the mounting groove 33.
Preferably, the shape and size of the through hole 31 are matched with the shape and size of the lower part of the sealing element 4, the shape and size of the positioning groove 32 are matched with the shape and size of the upper part of the sealing element 4, and the shape and size of the mounting groove 33 are matched with the shape and size of the sealing ring 5. Be used for matcing the sealing member through the design constant head tank, form the integral type structure, through design mounting groove and setting up the sealing member in the mounting groove, help promoting leakproofness, the waterproof nature of this through-hole position.
Preferably, the sealing member 4 is a screw, and the sealing member 4 is screwed with the through hole 31. Adopt screw and threaded connection's mode, easy dismounting and stable in structure after the installation, the leakproofness is good.
When the motor rotor needs to be disassembled, the lower shell 12 is disassembled firstly, the sealing element 4 is taken out, then a mandril penetrates from the through hole 31 to abut against the motor rotor 2, the motor rotor 3 is ejected downwards from the motor in a mode of striking the mandril downwards by a hammer, and the mandril is selected from rod tools with the diameter smaller than that of the through hole.
When the motor rotor needs to be installed, the motor rotor is installed from the lower part of the shell, and then the lower shell 12 and the sealing piece 4 are installed.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
